> What's the point in having leverage if you're not going to use it?

You act as if the audience is tied for Firefox. It's not. As soon as a user opens up another browser instead of Firefox to get access to the content, they are no longer leverage. And when you look at the audience as those with just Firefox alone, and those with a second browser, that audience dwindles to very few indeed.

You could make the argument that they then don't need to support the DRM because users can easily get around that. But then the problem there is that suddenly users are being punished. The content producers aren't suffering, just the users who are forced to switch browsers.
